Basic Aspects of Control System Design of Microprocessor Based Variable Speed Drives: Based on the examples of drives discussed in the foregoing, general outlines may be drawn for designing the…
Feedback Control in Drive System: Feedback Control in Drive System - A closed loop control of a variable speed drive system employing thyristor power converters is normally a discrete time…
Hardware Systems Versus Microprocessor Control: The Hardware Systems Versus Microprocessor Control control of electric drives offers the following advantages when compared to the dedicated hardware control. As has already been…
Control System Performance: From the foregoing discussion on control systems it can be seen that the behaviour of the control systems can be specified, based on several time domain specifications.…
Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a…
Features of Electric Drive System: Before applying advantageously the control principles to electric drive systems to adjust or improve their behaviour as a special case of control problem, it is…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
Base load and Peak Load on Power Station: The changing load on the power station makes its load curve of variable nature. Fig. 3.13. shows the typical load curve of…
